[CMake] Relink external project

[Evgeny Startsev]

I continue adapt "external_project"-style build for my projects. I found
out that my main project is not relinked, when external project on which it
depends was changed. How can i do that? In my opinion importing all
external projects libs is not good idea.

cmake -  2.8.3.
